====== KonText interface: Version history ====== {{ :seznamy:kontext-logo-vetsi.png?nolink&200|}} The corpus interface KonText is designed for general interaction with [[en:cnk:uvod|CNC corpora]]. A comprehensive list of KonText’s available functions can be found in the [[en:manualy:kontext:index|manual]]. KonText is an extended and visually modified version of the original NoSketch Engine application. It is developed by the [[http://ucnk.ff.cuni.cz/en/|Institute of the Czech National Corpus]] (Faculty of Arts, Charles University) and the [[http://ufal.mff.cuni.cz|Institute of Formal and Applied Linguistics]] (Faculty of Mathematics and Physics, Charles University) under the **GNU GPL 2** license (with Tomáš Machálek as the main developer). Just as the NoSketch Engine, KonText uses [[https://nlp.fi.muni.cz/trac/noske|Manatee]] as its backend. The version history overview below contains only the most signicant changes as seen from the end-user perspective. **A complete list of all changes and bug fixes can be found on [[https://github.com/czcorpus/kontext/releases|KonText's GitHub page]]** which also hosts a complete source code repository. ===== Release 0.17.0 ===== //Publication date: 17.2.2023// **User changes:** * Enhanced and refined **subcorpora** * By default, every subcorpus is available to all users, addressing issues with URLs shared between users * If a user does not provide a description, the subcorpus remains undiscoverable * A subcorpus can be archived in which case all the URLs are still functional but the subcorpus won't be listed in author's subcorpora (unless explicitly specified in listing filter) * On the concordance query page, users can create a **subcorpus draft** from selected text types for future use * Easily copy a subcorpus or create a new variant * A new function displays graphically the **dispersion** of a search term across the corpus data * Highlighted **translation equivalents** (as retrieved from the Treq application) directly in the concordance * Sharing **individual frequency tables through exported URLs** * When a frequency result page contains multiple tables, users can now easily obtain URLs for each table to share or publish the table * In the line selection function, users can navigate to the page with the **first selected line** * For manually categorized lines in extensive concordances where the first selected line starts far beyond the initial page, this feature enables automatic location of the first selection * Customizable "nice" backlinks allow other applications to reference KonText results (available for easier integration with other applications) * **Detection of overly time-consuming queries** for large corpora (typically the ones producing large result sets) and suggestion of an alternative corpus Technical changes: * core web application framework changed from Gunicorn+Werkzeug to [[https://sanic.dev/en/|Sanic]] * upgrade to React 18 * server backend rewritten with //async/awit// * checking of background tasks from the client side is now by default doe via WebSockets * support for Manatee 2.2xx * improved caching of frequency distribution results for faster navigation between result pages * moved from HTTP sessions stored on server to [[https://jwt.io/|JWT]] * possibility to apply individual "cutoff" for large concordances ===== Release 0.15.0 ===== //Publication date: 18. 12. 2020// User changes: * number of query types reduced to two: * advanced (equivalent to the original "CQL") * simple * multi-word search * optional support for regular expressions * optional (per corpus) default search attributes * new calendar-based widget for specifying date intervals in the "Restrict search" section of the main query form * **syntax_viewer** plug-in enhancement -- added support for new features of SYN2020 * new **query_suggest** plug-in providing interactive help with writing a query * **token_connect** plug-in can be now used also as a source for an alternative KWIC detail view * added a new module "formatted text" * **taghelper** plug-in now supports "key-value" tagsets and it is also possible to define multiple tagsets for a corpus * new option for displaying additional positional attributes (below the main text tokens) * possibility to set any positional attribute as the main one in the concordance view * more user-friendly "Corpus-specific settings" module * redesigned "Specify context" section of the main query form * possibility to perform more complex queries (billion-word corpora, aligned corpora when querying only the primary language) without the web-server's time limit constraint * an archived URL of a frequency distribution or a collocation can be now restored even for complex queries, regardless the web server time-out Technical changes: * server-side rewritten to Python 3 * added support for a new asychronous task processing backend [[https://python-rq.org/|Rq]]; the new backend is now the default one * client-side rewritten using the same framework as in [[manualy:wag|WaG]] * synchronization between the web server and the back-end worker queue rewritten in case of concordance calculation * changes in HTTP API ===== Release 0.13.0 ===== //Publication date: 9. 12. 2019// * rewrite of HTML templates to Jinja2 * transition to React.JS framework, which resulted mainly in extensive changes of the code and, to a lesser extent, also in user interface elements (e.g. corpus-specific view settings are now in three tabs) * preparing future functionality support ===== Release 0.12.0 ===== //Publication date: 30. 10. 2018// * translation equivalents based on Treq directly displayed in KonText for parallel corpora (set up for InterCorp v10 and v11) * CQL editor with syntax highlighting and basic value validation * mixed mode for attribute displaying (directly in text for KWIC, on mouse-over for other tokens) * sharing a named subcorpus and its description with other users * new filter functions * nested matches filter * first hits in docs filter * asynchronous exports with notification * improved keyboard navigation on the query result page * possibility to minimize individual text type boxes in the subcorpus form ===== Release 0.11.0 ===== //Publication date: 15. 12. 2017// * 2-dimensional frequency distribution with confidence intervals, including export of the data into Excel * added support for undo in the interactive text selection * added support for undo in the tag builder * improved query history * query history items can be archived with a custom name for later reuse * full query form is now saved which includes also selected texts * i.p.m. on demand calculation now works only in well-defined situations (i.e. subcorpus selected using the respective form, rather than a CQL query) * chart depicting line group proportions can be exported into Excel * word list * more convenient upload and in-browser editing of uploaded black/white-lists * it is now possible to go directly to the last page * added support for hiding individual columns of parallel corpora in concordance view ===== Release 0.10.0 ===== //Publication date: 11. 4. 2017// * for spoken corpora, concordance detail views are rendered as dialogues with clear indication of speaker turns and overlaps where audio can be played back by clicking the "speaker" icon * documents for subcorpora can newly also be selected according to user-defined text type ratios * individual query processing steps within the breadcrumb navigation can now be edited, allowing the user to change the parameters of previous operations * working corpus can now be changed without losing other information from the current query form * manually grouped concordance lines are now distinguished by colours * web page titles contain query information (for use in bookmarks and better browser history navigation) ===== Release 0.9.0 ===== //Publication date: 26. 9. 2016// * displaying of syntactic structures * asynchronous creation of subcorpora including a support for creating alignement-based subcorpora from parallel corpora * for attributes with long lists of values, a text input auto-complete function has been added for easier subcorpus creation * positional attributes can be displayed also on a mouse-over * navigation between concordance pages without reloading the whole page * frequency distribution and collocation results are now cached on server for faster pagination * user-defined numeric concordance line labels can be now renamed/removed * added support for displaying line numbers in a concordance ===== Release 0.8.0 ===== //Publication date: 8. 3. 2016// * concordance lines can have user-defined numeric labels attached for manual grouping/categorization * i.p.m. calculation for ad-hoc subcorpora (on demand; previous versions calculated i.p.m. from the whole corpus which could have been confusing) * support for creating subcorpora based on conditions that contain different structures (e.g. <speaker sex="male" /> and <session id="foo.+" />) * added a breadcrumb navigation depicting consecutive steps that led to the current query result ===== Release 0.7.0 ===== //Publication date: 5. 10. 2015// * new widget for corpus selection including favourite corpora, featured corpora etc. * rewritten "View" menu functions * enhancements of user interface usability (e.g. adding an aligned corpus)
