ICL00 at the NTCIR-12 STC Task: Semantic-based Retrieval Method of Short Texts
نویسندگان
چکیده
We take part in the short text conversation task at NTCIR-12. We employ a semantic-based retrieval method to tackle this problem, by calculating textual similarity between posts and comments. Our method applies a rich-feature model to match post-comment pairs, by using semantic, grammar, n-gram and string features to extract high-level semantic meanings of text.

BUPTTeam Participation in NTCIR-12 Short Text Conversation Task
Abstract This paper provides an overview of BUPTTeam’s system participated in the Short Text Conversation (STC) task of Chinese at NTCIR-12. STC is a new NTCIR challenging task which is defined as an IR problem, i.e., retrieval based a repository of postcomment pairs from Sina Weibo. In this paper, we propose a novel method to retrieve post result from the repository based on the following four...
متن کاملUSTC at NTCIR-12 STC Task
In this paper, we describe the system submitted by USTC team for the Short Text Conversation (STC) task of the NTCIR-12. We proposed transition-p2c, encoder-decoderReverse and joint-Train models for the STC task and submitted 5 official runs. The transition-p2c model provides transition probability between post and comment in word’s level which complements the TF-IDF feature. The encoderdecoder...

We describe how we build the system for NTCIR-13 Short Text Conversation (STC) Chinese subtask. In our system, we use the retrieval-based method and the generationbased method respectively. For the retrieval-based method, we develop several features to match the candidates and then apply a learning to rank algorithm to get properly ranked results. For the generation-based method, we first gener...

This paper provides an overview of BUPTTeam’s system participated in the Short Text Conversation (STC) task of Chinese at NTICR-13. STC is a new NTCIR challenging task which is defined as an information retrieval (IR) or natural language generation problem. In this paper, we propose a novel method to generate appropriate comments based on the following four steps: 1) preprocessing, 2) model bui...

This paper provides an overview of DeepIntell’s system participated in the Short Text Conversation (STC2) task of Chinese at NTCIR-13. Previous STC of NTCIR-12 is a conversation task which can be defined as an IR problem, i.e.,retrieval based a repository of post-comment pairs. STC2 of NTCIR-13 provided a transparent platform to compare the generation-based method and IR method via comprehensiv...
