The company, Messagepoint, has a cloud-based software platform that provides services for**businesses to enable easy communication with their customers. Examples of this type of communication include simple text messages on customer billing information and complete letter inserts that accompany communication between a business and its customers. The company-specific problem is the comparison of text messages in multiple languages for meaning similarity. Lexicon-based similarity algorithms have shown to work well in the context of word matching when exploring the semantic similarity space along word-relation hierarchies. However, these word-focused algorithms, are not very effective when computing semantic similarity for a larger set of words (such as sentences or paragraphs). Natural Language Processing methods will be integrated into the company's platform in order to generate a shallow semantic representation of the text messages generated by the company's software. This shallow semantic analysis will provide representations of the messages that can be compared for similarity of meaning.

该公司 Messagepoint 拥有一个基于云的软件平台，为**企业提供服务，以便与客户轻松沟通。此类通信的示例包括有关客户账单信息的简单文本消息以及企业与其客户之间通信所伴随的完整信件插入。公司特有的问题是比较多种语言的文本消息的含义相似性。当沿着单词关系层次结构探索语义相似性空间时，基于词典的相似性算法已被证明在单词匹配的上下文中运行良好。然而，这些以单词为中心的算法在计算较大单词集（例如句子或段落）的语义相似度时并不是非常有效。自然语言处理方法将集成到公司的平台中，以便生成公司软件生成的文本消息的浅层语义表示。这种浅层语义分析将提供可以比较含义相似性的消息表示。
