黑料不打烊

This database was established in 1964 under the name 鈥�Science Citation Index (SCI)鈩⑩�� as a product of the . From 1992 the database was acquired by Thomson Reuters and was soon renamed Web of Science (WoS DB). From 2016 WoS is owned by .

STRUCTURE AND CONTENT

is a platform consisting of a number of separate specialized databases (indexes), but the most important of these are concentrated in the part of the platform. Currently more than 21 000 journals, of which more than 12 000 journals have citation indicators, are indexed in WoS Core Collection.

The goal of WoS founder Eugene Garfield was to collect data of only the highest quality international scientific output. Therefore, WoS is a selective DB, meaning that only journals meeting strict selection criteria are indexed and periodically re-evaluated. Nevertheless, the content of the WoS DB covers all major disciplines, but in different proportions: the coverage of life, biomedicine, physical and technological sciences is the most comprehensive, while the coverage of Social Sciences, and especially Humanities, is much narrower and considered insufficient for reliable evaluations and data analyzes.

ACCESS TO CONTENT

Long years of use and domination have granted WoS with the title of “gold standard” which also lead to the inevitably increased price for its subscription. As a result, academic institutions typically cannot afford to subscribe the entire WoS DB platform. Therefore, institutions usually subscribe only to a part (often with additional content access restrictions).

The content of WoS Core Collection indexes (elsewhere also referred as Editions) available to 黑料不打烊 community members and the additional access restrictions on their depth, according to the subscription agreement renewed on April 2021, are presented in table 1.

Table 1. The content of the WoS Core Collection and its depth limits available to the university鈥檚 community.

Content access restrictions become especially important when evaluating the author’s h-index values in WoS DB, since they are calculated only from the user-accessible DB content (both regarding publications and citation data).

ADDITIONAL FEATURES

WoS DB users can听create their personal accounts:

Users who create free WoS accounts can additionally:

• save performed searches and their settings;
• subscribe to new results based on performed searches (alert);
• select and create individual lists of publications (marked list) that can be saved (up to 50 lists can be saved);

These functions are accessible and may be configured via the expanding signed-in user menu at the left-hand-side of the window:

The lists of the last performed searches (Recent searches), most recently set alerts (Latest alerts), and according to the user鈥檚 search history recommended publications (Recommended for you) are also provided on the home page of the signed-in user.

Users are advised to create one WoS account and use it for all WoS products:

• User registration is required to use the InCites tool and download the lists of WoS indexed journals from the
• A personal account and registration are not required to use JCR and ESI tools. Registration is recommended if you want to create and manage reports saved in ESI folder, subscribe to a newsletter (alert), save the results or search settings, and perform other additional functions provided in these tools.

Important! First you need to create your WoS account in 黑料不打烊 computer network. Later, it is possible to connect and work with all WoS tools outside the 黑料不打烊 computer network.

Users can choose between Advanced Search and Smart Search in the updated WoS interface.

The Basic Search allows users to search for publications (Documents), Cited References, and Authors (Researchers):

PUBLICATION (DOCUMENT) SEARCH

Document (and cited reference) search can be performed only within the听听part, in the content of all available DB sections, or in individual regional or specific document DBs听(in these cases, the search and filtering options may be narrower than searching within 奥辞厂听Core Collection听content).

In 2023鈥�2025, WoS DB was expanded by adding additional resources of specific documents (听补苍诲听), grants ()听补苍诲听听collection, which includes journal output from open metadata platforms such as听听补苍诲听.

It should be noted that selecting the option听All Databases听is not enough for the听Preprint Citation听Index or听Research Commons听to be included in the search. The user must additionally choose to include these collections in the search results window:

Upon selection to search within only听奥辞厂听Core Collection听part, the search context can be further specified by selecting only听particular indexes听(Editions):

Publications can be searched:

• within various data of document鈥檚 entry (by title, keywords, author, institution, title of the publication or publisher, etc.)
• by adding additional search fields (+Add row), which enables to search within several different fields at the same time
• the search can be additionally limited to a certain time period (by听publication听or by听indexing听(inclusion in WoS DB) date)
• Advanced search听(Query Builder)听is also available
• a search query can be formulated using abbreviations and search operators

Obtained results (lists of publications)听can be:

• further narrowed/specified by applying various filters (Refine results)
• added to list (Add To Marked List)
• exported in various formats (Export)
• further analyzed (Analyze Results)
• their citation data reports can also be generated (Citation Report)

Filter values听displayed next to search results can be exported in XLS format (Export Refine).

CITED REFERENCE SEARCH

CITATION CONTEXT

A part of cited references listed in WoS indexed publications are available with additional information indicating the purpose, context and the part of the publication where the reference have been mentioned.

This additional information is provided for the publications classified by a new听citation context scheme, aiming to help assess the intents of the authors using these literature sources.

• Background听鈥� previously published research that orients the study published in the analyzed publication within a scholarly area.
• Basis听鈥� references that report the data sets, methods, concepts and ideas that the author was using for his/her work directly or on which the work was based.
• Support听鈥� references which have similar results to the ones published in the analyzed publication. This may also refer to similarities in methodology or in some cases replication of results.
• Differ听鈥� references which reports differing results compared to the ones published in the analyzed publication. This may also refer to differences in methodology or differences in sample sizes, affecting results.
• Discuss听鈥� references allowing the study published in the analyzed publication to be discussed in more details and/or broader context.

Publications whose sources cited in the bibliography are provided with citation context information are marked with the听Enriched Cited References听tag both in the publication lists and on the publication page itself:

It should be mentioned, that the results obtained by听document search听can be also narrowed by this criterion:

Even more detailed information on the cited references listed in the听Enriched Cited References听tagged publication is provided in the听dot-plot diagram, included on the tagged publication鈥檚 page below the main information, just above the list of cited references.

In this diagram, every听dot听represents the听cited reference, oriented according to the citing intent (vertical axis) and structural place in the text (horizontal axis):

Hovering the mouse over a dot displays the title of the cited source and the link provided below it (View in-text mentions) leads to the cited source in the list along with an indication of a structural part of the publication where the source was cited and the specific passage of the text mentioning the source:

WoS DB allows to assess not only the purpose and the place of the literature sources mentioned in the publication, but also to听evaluate the impact of the particular publication made on other studies. If a publication was at least once cited by other WoS indexed publications classified by the new citation context scheme, on the right hand side on the publications page the听Citing items by classification听graph听is displayed:

This graph is听interactive听and clicking on any of its elements redirects to the list of the corresponding citing publications, where below the entry of every publication not only a structural part of the citing source where the analyzed publication was cited, but also a specific passage of the text mentioning the publication (In-text mentions), are indicated:

PUBLICATION COMPARISON METRICS听

From 2024听听publication records (not older than 1980) include a link to the听Comparison metrics panel,听which provides data from the听听tool.

This feature helps to evaluate a selected publication based on its citation count in a broader context. The听Comparison metrics听panel provides 5 types of publication data:

• Percentage of documents of the same type, from the same category and published in the same year that have a lower citation count than the selected paper (Percentile in subject area).
• Ratio of a document’s actual times cited count to the expected count for a document of the same type, from the same category, and published in the same year (Category Normalized Citation Impact).
• Expected number of citations calculated from other items of the same type published in the same subject categories and year (Category expected citations).
• Ratio of a document’s actual times cited count to the expected count for a document of the same type, from the same journal, and published in the same year (Journal Normalized Citation Impact).
• Expected number of citations calculated from other items of the same type published in the same journal and year (Journal expected citations).

These data can be exported in PDF format.

AUTHOR SEARCH

You can search for authors:

• by author’s last name and first name/initials (Name search); it is possible to add additional field(s) and search by the main and possible alternative variants of the author’s surname / name at the same time
• by the institution represented by the author (Organization)
• authors can also be searched by their Researcher ID or ORCID identifiers (Author identifiers).

The听search results听include the听author听or a听list of them听(if there are multiple authors with the same last name):

• Additional information about the author’s affiliation, number of publications, the period of publication, and the journals in which the author has published most often, is also provided in the search results.
• Search results can be refined by filtering by author names, author profile status,听WoS听categories, affiliations, countries/regions,听Highly Cited Researcher听award year, award category and other听quick filters.
• If individual results include data from the same author, you can tag and view data from multiple authors grouped into one profile.

Important!听In WoS individual author profiles are generated by an automatic algorithm, so profiles may be incomplete and/or erroneous (e.g., publications belonging to one author may be split into two profiles, and/or some publications may be unassigned/incorrectly assigned to a specific author). Therefore, it is advisable to review and verify the information provided in the author’s profile.

SMART SEARCH

黑料不打烊 community members can use the following tools accessible from WoS DB:

• 听鈥� is a tool for evaluation of journals quality. It can be used to search for WoS CC indexed journals, review their citation indicator values and other information.
• 听鈥� is a tool for assessing the most relevant and impactful research fields and trends.
• 听is a tool to facilitate the analysis of WoS indexed research output by evaluating publication and citation counts and their distribution by various aspects and in different contexts.听NEW!听听鈥� a module of听InCites, which helps to discover emerging research topics.
• 听is an artificial intelligence-powered tool that helps perform tasks involving information search and analysis more efficiently.

Important!听All WoS analysis tools use data only of听听indexed publications and citations (data from specialized and regional DBs are not included). Accordingly, it is important to consider the additional possible restrictions on accessible WoS Core Collection content depth, as they often apply not only to the availability of publications, but also to the availability of citation data.

JOURNAL CITATION REPORTS (JCR)

听is an analytical tool intended for assessing the quality of journals. It allows to search the journals indexed in the 奥辞厂听Core Collection听databases and view their citation data and metrics, the relationship between article and journal citations, and other journal information. JCR provides transparent, publisher-neutral data and metrics that provide insight into the journal鈥檚 role and impact on the global research community.

Starting with the 2021 edition听JCR has been generally renewed. Apart from the drastically changed听user interface听(both regarding structural layout and design), several听conceptual and/or functional changes听of the tool have also been implemented, with the most significant ones being:

• Expanded coverage of journals: now JCR also includes publications indexed in the听听and the听. The inclusion of these indexes in JCR (and also other WoS analysis tools) provides a broader and more representative coverage. This extension of JCR content is based on the fact that journals included in the AHCI and ESCI are subject to the same stringent quality requirements as the content of other main WoS indexes (e.g.,听听补苍诲听).
• JCR citation reports are generated using citation data from all听 奥辞厂听Core Collection听journal indexes, including citation data from the听Arts & Humanities Citation Index (AHCI)听and the听Emerging Sources Citation Index (ESCI). From 2021 JCR also听听publications and citations data.
• JCR journal profiles now presents more detailed information regarding听听by indicating all types of publishing models employed by the journal, and providing publication and citation data (and their graphical representations) of articles representing each of these publishing models.

More information on the听JCR renewal and improvements听implemented in 2021 can be found here听

The JCR provides a rich set of听journal citation indicators, including the听, along with their trends.

The most important changes of indicators provided in JCR:

• Starting with the 2023 JCR edition, the main WoS journal citation indicator听听is calculated听for all听JCR (WoS听) journals, including ones indexed in the听听and the听.
• From 2021, an additional听听is calculated for all JCR (WoS听) journals, including ones indexed in AHCI and ESCI, and is displayed in all JCR journals鈥� profiles. JCI is a citation indicator normalized by discipline, developed aiming to provide opportunities for evaluation and direct comparison of quality of the journals representing all major disciplines (which is not possible to achieve by using JIF indicator).听Detailed information about JCI calculation and interpretation is available here听.
• From 2023 edition, the JIF is displayed with only one decimal place instead of three (does not apply for the JIF values of the previous years).

Extensive information听about JCR indicators (JIF and JCI)听鈥� their calculation, application, and possible exceptions, is provided here听

Detailed information on journals included in the JCR and their citation data for recent and previous years are provided in the听JCR journal profiles. The latest values of journal citation indicators and journal ranks in WoS categories can also be viewed in the publication list data by clicking on the activated (blue) source title (if the title is not active, the source is not included in JCR, and it does not have JCR profile and citation indicators), and also from the individual publication entry, in the听Journal Information section听(at the bottom of the page).

ESSENTIAL SCIENCE INDICATORS

听is an analytical tool intended to assess the most relevant and popular research fields and their global trends based on data from the 奥辞厂听Core Collection. The ESI tool is most useful for comparing research outputs, identifying the most popular research fields and trends, ranking the best authors, institutions, countries, journals, and detecting the most impactful publications.

ESI data used for calculations

Publications:听ESI analyzes data from scientific and review articles indexed by the听听补苍诲听听(letters, editorials, corrections, and similar types of publications are not highly cited and thus are not included in ESI data calculations).

Citation:听Citation calculations include citations from articles, reviews, documents, and research notes published in journals indexed in听, the听, and the听. Citations from books or book chapters, conference proceedings, letters, editorials, corrections, and similar documents types, and citations from articles published in sources indexed in other WoS indexes, including听, are not included in reports generated by the ESI.

Data period: Data for 10 years are analyzed on a sliding principle (data for the first year are discarded when full data for year 11^th听year is accumulated). Ratings and citations are updated every two months.

Research fields (categories): ESI tool employs an individual categorization of the research fields that is not related/dependent on the WoS Category Classification Scheme. ESI classification consists of 22 broad categories that do not overlap, i.e., each evaluated object in the ESI is assigned to only one science category.

Criteria for inclusion: Only authors, institutions, countries, journals and articles having the highest citation rates are included in the ESI. In order to be included in the ESI these entities must meet certain citation thresholds within a particular science category (Table 1).

Table 1.听Citation thresholds that determine the inclusion of entities in ESI.

Definitions of the main concepts:

• 鈥�Highly Cited Papers鈥� 鈥� articles with a high citation rate, which are among the 1% most cited articles compared to other articles published in the same year and in the same category.
• 鈥�Hot papers鈥� 鈥� articles published in the last 2 years. If the citation of these articles accounted for 0.1% of the total citation of articles in the same field and published at the same time in the WoS Core Collection within 2 months, then such articles fall within the ESI. The evaluation of articles for their inclusion in the ESI is performed every two months when citation data updates are performed.
• 听鈥�Top papers鈥� 鈥� the sum of the publications attributable to 鈥�Highly Cited Papers鈥� and听鈥�Hot papers鈥�. If a publication meets the criteria for both categories, it will only appear once in the 鈥�Top papers鈥� results.
• 听鈥�Research Fronts鈥� 鈥� groups of the most cited articles in a specialized field/topic published in the last 5 years (called 鈥�Core Documents鈥�). The assignment of publications to research fronts is not linked to the ESI’s classification scheme. Therefore, Research Fronts can be used as an alternative way of classifying the most cited publications.

鈥�Highly Cited Papers鈥� and 鈥�Hot papers鈥� allows to readily identify the most influential research in specific areas. Publications that meet the aforementioned criteria are also indicated with special icons in the 奥辞厂听Core Collection听search results or other publication lists:

Usage

The usage of ESI tool does not require to have WoS account. However, the tool, as well as all other WoS content and tools, can be accessed only from 黑料不打烊 network or by using VPN service.

For the most effective use of ESI it is required firstly to assess what will be analyzed (authors, institutions, journals, countries, publications), and what criteria will be applied for including the results in the report.

INCITES BENCHMARKING & ANALYTICS (INCITES)

听鈥� is a research evaluation tool for analyzing publication and citation data. It is primarily intended for administrators of academic institutions and government authorities to analyze the scientific productivity and output quality of institutions (or other evaluated entities) and to compare data in both national and international contexts.

Usage

InCites听is the only WoS tool for which it is not enough to work from 黑料不打烊 computer network or with VPN –听user registration is required听(it is advisable to create a single WoS account and use it for all WoS products).

A video guide explaining the听

InCites听tool is designed to facilitate data analysis for evaluation purposes and to generate reports of evaluated entities (researchers, organizations, publishers).

With听InCites听tool various entities can be analyzed:

• Researchers听鈥� allows to evaluate the research results of individual researchers.
• Organizations听鈥� intended for the evaluation of organizations in various aspects. For example, for evaluation of the collaboration levels between institutions, or for comparison of organizations performance in different research areas.
• Departments听鈥� allows to evaluate and compare organization鈥檚 departments.
• Locations听鈥� allows to evaluate the trends of international cooperation, and to determine and compare the dominant research areas in different countries.
• Research Areas听鈥� allows to identify the most developed research areas and the impact of performed research within your own and other institutions.
• Publication Sources听鈥� allows to identify sources most commonly used for publishing by the institution’s researchers.
• Funding Agencies听鈥� helps funders, analysts, researchers and publishers to assess the impact of their funded research.

The tool also provides a range of analysis听templates听designed to answer specific questions, and a Resource Center (a question mark at the bottom of the right side) accompanying the user through all analysis steps and providing all the necessary information.

Data coverage
InCites听uses data from publications and citations (since 1980; in听Research Horizon Navigator听module 鈥� from the last 5 years) indexed in all main听听indexes, which are updated monthly (usually at the end of the month).

Important!听In default setup data from publications and citations indexed by听Emerging Source Citation Index听(ESCI) are not included in听InCites听analyzes, but may be included optionally.

Important!听Some data in WoS database and听InCites听tool may not coincide due to the narrower extent of the data used in听InCites.

In 2024,听InCites听tool was supplemented with the听Research Horizon Navigator听module, which can help to:

• Discover emerging research topics.
• Track the contribution of organizations in various research areas.
• Identify authors of foundational papers.
• Better understand interdisciplinarity of various research topics, etc.

WEB OF SCIENCE RESEARCH ASSISTANT

听is an AI tool with a broad range of features, that enables easier and more efficient use of the WoS database.

The tool uses abstracts, metadata, and citation data of publications indexed in the Web of Science Core Collection, as well as information from WoS author profiles.

A link to Research Assistant is provided on the听听homepage.

The tool can be used by submitting a natural language query (including in Lithuanian or another language) or by selecting one of the modules designed for a specific task.

When a query is entered into the prompt box on the听Research Assistant鈥檚听main page, the tool identifies relevant publications, selects the 25 most suitable ones, and鈥攂ased on their abstracts (not necessarily all of them)鈥攇enerates a short text with references to the sources used.

Below the text, a list of the 25 key publications is provided, along with links to various visualizations of the selected publication鈥檚 data:

• Co citation map听that visually represents citation links among publications.
• Enriched cited references map听that shows where citations appear in the selected publication鈥檚 text and what is the intent of each citation.
• Citing items by classification chart听that shows how the selected publication is cited in other publications.

Further down, links to full lists of relevant publications (View all results in Web of Science Core Collection) and preprints (View related preprints) are provided, both of which can be filtered, analyzed and exported.

Additionally, Research Assistant matches the user鈥檚 query to a specific research field and provides links to:

• Documents over time graph听that shows the number of publications in this research field for each year.
• Topic map听that illustrates the relationships between relevant research topics and concepts.
• List of听top authors听representing the assigned research field.
• Follow up query suggestions.

Research Assistant听accepts a wide range of queries 鈥� they do not have to be directly related to the information contained in publication abstracts. This tool also allows to submit questions about institutions (e.g. which institutions published the most articles in the field of bioengineering in 2025?), researchers (e.g. which researchers are the most cited in the field of geodesy?), and publications (e.g. which articles about climate change have been cited more than 5,000 times?).

Depending on the type of query, the response may be provided not in the form of a text, but as a list or various types of visualizations.

Research Assistant also includes three modules that use a conversational workflow to guide the user through specific tasks:

• Module听Topic Explorer听helps to learn about various aspects of a research topic by providing definitions, identifying relevant review articles and key authors, generating various types of visualizations, and more.
• Module听Literature review听can synthesize the relevant literature, identify research gaps and hotspots, and suggest hypotheses for potential research.
