胡泳:AI倾向于加强人类对话的缺陷(图)
AI 人类对话 缺陷
2023/3/9
自然语言文本中存在大量否定性与不确定性语言现象,反映了人类在使用语言表达观点时的态度,亦或者语言信息本身的可信度。语言的否定性指,由否定运算符对命题本身或其某一方面的语义进行了反转;语言的不确定性指,包含了情态、言据性、或然性、主观性等任何一类语义,介于肯定和否定语义之间。识别并理解自然语言的否定性与不确定性,对更深层次的自然语言理解具有重要意义,并且随着自然语言处理领域相关应用的不断增长,该研究...
基于表示学习的文本情感分析研究
文本情感分析 表示学习 面向文本情感分析的词向量 深层记忆网络 切分分类联 合模型
2016/11/23
文本情感分析是自然语言处理领域的热点问题之一,目的在于自动地从文本中发现和归纳主观情感信息。情感分析的一个核心问题是如何有效地表示各层次(如词语、句子、篇章)文本的情感语义,其重要性主要体现为两个方面。一方面,理解文本的情感需要让机器理解人类语言中所表达的语义,文本的语义表示是人类和机器之间信息传递的桥梁;另一方面,目前基于机器学习的方法在多个层次的情感分析任务上取得了非常出色的效果,而一个机器学...
Static Type Inference in a Dynamically Typed Language
Static Type Inference Dynamically Typed Language
2016/5/25
We present a type inference system for FL based on an operational, rather than a denotational, formulation of types. The essential elements of the system are a type language based on regular trees and...
Query Understanding Enhanced by Hierarchical Parsing Structures
query understanding semantic tagging linguistic parsing
2016/1/23
Query understanding has been well studied in the areas of information retrieval and spoken language understanding(SLU). There are generally three layers of query understanding: domain classification, ...
Natural language processing systems, even when given proper syntactic and semantic interpretations, still lack the common sense inference capabilities required for genuinely understanding a sen-tence....

Automatically recognizing a large number of action cat-egories from videos is of significant importance for video understanding. Most existing works focused on the design of more discriminative featur...
Events of various sorts make up an important subset of the entities rel-evant not only in knowledge representation but also in natural language processing and numerous other fields and tasks. How to r...
Semantic Information Extraction for Improved Word Embeddings
Semantic Information Extraction Improved Word Embeddings
2016/1/22
Word embeddings have recently proven useful in a number of different applications that deal with natural language. Such embeddings suc-cinctly reflect semantic similarities between words based on thei...
Lexvo.org: Language-Related Information for the Linguistic Linked Data Cloud

2016/1/22
Lexvo.org brings information about languages, words, and other linguistic entities to the Web of Linked Data. It defines URIs for terms, languages, scripts, and characters, which are not only highly i...
The task of event coreference resolution plays a critical role in many natural language processing applications such as information extraction, question answering, and topic detection
and tracking. I...

We propose a framework for using multiple sources of linguistic information in the task of
identifying multiword expressions in natural language texts. We define various linguistically
