Constrained Language Models for Interactive Poem Generation

Aris Xanthos, Andrei Popescu-Belis, Gabriel Luthier, Simon Mattei, Alejandro Ramírez Atrio

This paper describes a system for interactive poem generation, which combines neural language models (LMs) for poem generation with explicit constraints that can be set by users on form, topic, emotion, and rhyming scheme. LMs cannot learn such constraints ...

Subword Mapping and Anchoring across Languages

Andrei Popescu-Belis

State-of-the-art multilingual systems rely on shared vocabularies that sufficiently cover all considered languages. To this end, a simple and frequently used approach makes use of subword vocabularies constructed jointly over several languages. We hypothes ...

Adaptive sentiment-aware one-class collaborative filtering

Andrei Popescu-Belis, Nikolaos Pappas

This paper presents a novel application of sentiment analysis to recommender systems relying on explicit one-class user feedback (favorites or likes), namely joint models of unary feedback and sentiment of free-form user comments. This combination is achie ...

Disambiguating Discourse Connectives for Statistical Machine Translation

Andrei Popescu-Belis, Thomas Meyer

This paper shows that the automatic labeling of discourse connectives with the relations they signal, prior to machine translation (MT), can be used by phrase-based statistical MT systems to improve their translations. This improvement is demonstrated here ...

Pronoun Translation and Prediction with or without Coreference Links

Andrei Popescu-Belis, Lesly Sadiht Miculicich Werlen

The Idiap NLP Group has participated in both DiscoMT 2015 sub-tasks: pronoun-focused translation and pronoun prediction. The system for the first sub-task combines two knowledge sources: gram matical constraints from the hypothesized coreference links, and ...

Query Refinement Using Conversational Context: A Method and an Evaluation Resource

Maryam Habibi, Andrei Popescu-Belis

This paper introduces a query refinement method applied to queries asked by users during a meeting or a conversation. The proposed method does not require further clarifications from users, to avoid distracting them from their conversation, but leverages i ...

Computing text semantic relatedness using the contents and links of a hypertext encyclopedia

Majid Yazdani, Andrei Popescu-Belis

We propose a method for computing semantic relatedness between words or texts by using knowledge from hypertext encyclopedias such as Wikipedia. A network of concepts is built by filtering the encyclopedia's articles, each concept corresponding to an artic ...

Automatic Identification of Discourse Markers in Multiparty Dialogues: An In-Depth Study of Like and Well

Andrei Popescu-Belis

The lexical items 'like' and 'well' can serve as discourse markers (DMs), but can also play numerous other roles, such as verb or adverb. Identifying the occurrences that function as DMs is an important step for language understanding by computers. In this ...
