Feature Selective Likelihood Ratio Estimator for Low- and Zero-frequency N-grams

no code implementations5 Nov 2021 Masato Kikuchi, Mitsuo Yoshida, Kyoji Umemura, Tadachika Ozono

However, because this method deals with a large number of discrete values, the running time and memory usage for estimation are problematic.

Unified Likelihood Ratio Estimation for High- to Zero-frequency N-grams

no code implementations3 Oct 2021 Masato Kikuchi, Kento Kawakami, Kazuho Watanabe, Mitsuo Yoshida, Kyoji Umemura

A naive estimation approach that uses only $N$-gram frequencies is sensitive to low-frequency (rare) $N$-grams and not applicable to zero-frequency (unobserved) $N$-grams; these are known as the low- and zero-frequency problems, respectively.

Analysis of Short Dwell Time in Relation to User Interest in a News Application

no code implementations27 Dec 2020 Ryosuke Homma, Yoshifumi Seki, Mitsuo Yoshida, Kyoji Umemura

We hypothesize that content with short dwell time is not always low quality and does not always have low user engagement, but is instead related to user interest.

Journal Name Extraction from Japanese Scientific News Articles

no code implementations11 Jun 2019 Masato Kikuchi, Mitsuo Yoshida, Kyoji Umemura

We hypothesize that a journal name is likely to occur in a specific context.

Polysemy Detection in Distributed Representation of Word Sense

no code implementations26 Sep 2017 Kana Oomoto, Haruka Oikawa, Eiko Yamamoto, Mitsuo Yoshida, Masayuki Okabe, Kyoji Umemura

In this paper, we propose a statistical test to determine whether a given word is used as a polysemic word or not.
