A Corpusdata Retrieval Index using Lucene for Look-Ups
Description
Krill is a Lucene based search engine for large annotated corpora, used as a backend component of the KorAP Corpus Analysis Platform at the IDS Mannheim.
! This software is in its early stages and not stable yet! Use it on your own risk!
Features
Krill is the reference implementation for KoralQuery, covering most of the protocols features, including ...
Fulltext search
"Find all occurrences of the phrase 'sea monster'!"
"Find all case-insensitive words matching the regular expression /krak./!"*Token-based annotation search
"Find all plural nouns in accusative!"Span-based annotation search
"Find all nominal phrases!"Distance search
"Find a verb that is in a distance of five words to the noun 'Squid'!"Positional search
"Find a noun at the end of a nominal phrase!"Nested queries
"Find a determiner at the beginning of a named entity, that occurs at the end of a sentence!"and many more ...
Multiple annotation resources; Virtual Collections; Partial highlightings; Support for overlapping spans; Relational queries; Hierarchical queries ...
Prerequisites
Java 7 SDK, Git, Maven 3. Further dependencies are resolved using Maven.
Setup
To fetch the latest version of Krill ...
$ git clone https://github.com/KorAP/Krill $ cd Krill
To run the test suite ...
$ mvn clean test
Caveats
Krill operates on tokens and is limited to a single tokenization stream. Token annotations therefore have to rely on that tokenization, span annotations have to wrap at least one token. Punctuations are currently not supported. The order of results is currently bound to the order of documents in the index, but this is likely to change.
