Changelog

Major changes to TCSE by version. Maintenance releases that do not change search functionality may be omitted.

v13

Version 13 adds a layer of typed abstraction to Advanced Search: noun chunks are no longer just placeholders, but slots you can constrain and cross-reference. See Advanced Search Query Syntax for full details.

  • Typed noun-chunk slots (v13.1.0) — _{COND} constrains a chunk by its head (root) token: _{pron} matches chunks headed by a pronoun, _{-pron} its exact complement. Example: [give|send|tell] _{pron} _ retrieves ditransitives with pronominal recipients.
  • Entity-typed chunk conditions (v13.2.0) — _{%PERSON} matches a chunk headed by a PERSON entity; types combine with | (_{%PERSON|%ORG}) and mix with other conditions (_{pron|%PERSON} for "a human referent").
  • Lemma echo (v13.3.0, extended in v13.4.0) — Bind a slot's lemma with :N and refer to it later with =N, so that cross-slot identity becomes a single query: {noun:1} [after] _{=1} retrieves study after study, and {adv:1} [and] {=1&adv} retrieves over and over.
  • Chunk-head lemma conditions (v13.5.0) — _{[life]} matches chunks whose root lemma is life, so cognate objects come out directly: [live]{verb} _{[life]}.
  • Chunk-head lemma disjunction (v13.6.0) — the lemma condition accepts alternatives: _{[part|role]} matches chunks headed by part or role, so [do|play|take]{verb} _{[part|role]} covers light-verb pairs in one query. _{-[part|role]} matches chunks headed by neither.

v11–v12

User Interface

  • Multilingual UI — Interface available in English, Japanese (日本語), Chinese (中文), and Korean (한국어). Use the language buttons on any page to switch.
  • Streamlined search workflow — The RESET button has been removed. You can now start a new search at any time by simply entering a query and clicking SEARCH, just like a regular search engine.

New Search Features

  • KWIC concordance view — Toggle between list and KWIC (Key Word In Context) display modes for linguistic analysis
  • Named entity (NER) search — Use %PERSON, %ORG, %GPE, %DATE, etc. in Advanced Search to find named entities
  • Collocation analysis — MI, t-score, and DP statistics with lemma-based grouping in Collocation mode
  • Collocation network — Interactive force-directed graph visualization of word co-occurrence relationships
  • Export search results — Download token search results as TSV (ZIP) or JSON with context, linguistic annotations, and translations for research use

Collocation & Visualization

  • NER-enhanced n-grams — Named entities replaced with %TYPE labels (e.g., %PERSON said, in %GPE) for entity-aware frequency analysis
  • Network zoom slider — Zoom control (50%–200%) replaces scroll-based zooming for more precise graph navigation
  • Text highlight default off — Keywords and discourse markers highlighting is now off by default for a cleaner transcript view

Construction & Data

  • Construction category filter — Patterns categorized into Phrasal Verb, Idiom, Grammatical, Collocation, Discourse, and NER Pattern, with filter UI
  • 1,167 construction patterns — Including pseudo-cleft, resultative, NER patterns, adjective-subjectivity constructions, and other linguistic structures
  • 6,419 TED Talks — Over 1,100 new talks added since v10
