Konferensbidrag (refereegranskat)abstract
- We present an algorithm for incremental statistical parsing with Parallel Multiple Context-Free Grammars (PMCFG). This is an extension of the algorithm by Angelov (2009) to which we added statistical ranking. We show that the new algorithm is several times faster than other statistical PMCFG parsing algorithms on real-sized grammars. At the same time the algorithm is more general since it supports non-binarized and non-linear grammars. We also show that if we make the search heuristics non-admissible, the parsing speed improves even further, at the risk of returning sub-optimal solutions.

A Bilingual Treebank for the FraCaS Test Suite
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We have created a bilingual treebank for 99% of the sentences in the FraCaS test suite. The treebank is built together with an associated bilingual English-Swedish lexicon written in the Grammatical Framework Resource Grammar. The original FraCaS sentences are English, and we have tested the multilinguality of the Resource Grammar by analysing the grammaticality and naturalness of the Swedish translations. 86% of the sentences are grammatically and semantically correct and sound natural. About 10% can probably be fixed by adding new lexical items or grammatical rules, and only a small amount are considered to be difficult to cure.

Konferensbidrag (refereegranskat)abstract
- We have created an open-source bilingual treebank for 99% of the sentences in the FraCaS test suite. The treebank was built in conjunction with associated English and Swedish lexica written in the Grammatical Framework Resource Grammar. The original FraCaS sentences are English, and we have tested the multilinguality of the Resource Grammar by analysing the grammaticality and naturalness of the Swedish translations. 86% of the sentences are grammatically and semantically correct and sound natural. About 10% can probably be fixed by adding new lexical items or grammatical rules, and only a small amount are considered to be difficult to cure.

A free and open-source tool that reads movie subtitles aloud
- 2012
-
Ingår i: SLPAT'12: 3rd Workshop on Speech and Language Processing for Assistive Technologies.
-
Konferensbidrag (refereegranskat)abstract
- We present a simple tool that enables the computer to read subtitles of movies and TV shows aloud. The tool extracts information from subtitle files, which can be freely downloaded from the Internet, and reads the text aloud through a speech synthesizer. There are three versions of the tool, one for Windows and Linux, another for Mac OS X, and the third is a browser-based HTML5 prototype. The tools are freely available and open-source. The target audience is people who have trouble reading subtitles while watching a movie, including elderly, people with visual impairments, people with reading difficulties and people who wants to learn a second language. The application is currently being evaluated together with user from these groups.

Editing Syntax Trees on the Surface
- 2011
-
Ingår i: Nodalida'11: 18th Nordic Conference of Computational Linguistics.
-
Konferensbidrag (refereegranskat)abstract
- We describe a system for interactive modification of syntax trees by intuitive editing operations on the surface string. The system has a graphical interface, where the user can move, replace, add, and in other ways modify, words or phrases. During editing, the sentence is kept grammatical, by automatically rearranging words and changing inflection, if necessary. This is accomplished by combining constraints on syntax trees with a distance measure between trees.

GRASP: Grammar-based Language Learning
- 2010
-
Ingår i: SLTC-2010, 3rd Swedish Language Technology Conference.
-
Konferensbidrag (refereegranskat)abstract
- We are developing a pedagogical tool to support language learning and training for children with communicative disabilities. The system has a graphical interface, where the user can move, replace, add, and in other ways modify, words or phrases. The system keeps the sentence grammatical, by automatically rearranging the words and changing inflection, if necessary. In this way we hope that the system stimulates the child to explore the possibilities of language.
