Text Analytics: Cross-Lingual Link Discovery
Cross-lingual text analysis is an essential research topic in both Natural Language Processing (NLP) and Information Retrieval (IR), and it has long been well received in the research communities.This seminar course studies the task of Cross-lingual link discovery (CrossLink), which has become a hot topic in the recent years.
CrossLink is a task of “automatically finding potential links between documents in different languages,” where such system “actively recommends a set of meaningful anchors in the source document and … establishes links with documents in other languages” (NTCIR-9 CrossLink task description).
The course consists of two parts. The general approaches to CrossLink will be addressed in student presentations during the first few weeks of the class. In the second part, as hands-on experiments, all students are expected to participate in an in-class evaluation workshop; until the end of the semester, students will develop their own CrossLink system using a subset of English and German Wikipedia corpus and submit runs on a set of test topics. Submissions will be evaluated automatically and the systems will be analyzed based on their results.
Students are expected to perform the following tasks:
- present a talk on a previous work of their choice
- develop their own CrossLink system
- submit a run produced by their CrossLink system
- present a talk and submit a report on their CrossLink system
- Lectures are on Thursdays, 13:30 – 15:10 in S2|02|C110.
- This course is instructed in English, and student presentations and term papers are to be conducted in English.
