    Abstract
    Knowledge-enhanced short-text matching has been a significant task attracting much attention in recent years. However, the existing approaches cannot effectively balance effect and efficiency. Effective models usually consist of complex network structures leading to slow inference speed and the difficulties of applications in actual practice. In addition, most knowledge-enhanced models try to link the mentions in the text to the entities of the knowledge graphs-the difficulties of entity linking decrease the generalizability among different datasets. To address these problems, we propose a lightweight Semantic-Enhanced Interactive Network (SEIN) model for efficient short-text matching. Unlike most current research, SEIN employs an unsupervised method to select WordNet's most appropriate paraphrase description as the external semantic knowledge. It focuses on integrating semantic information and interactive information of text while simplifying the structure of other modules. We conduct intensive experiments on four real-world datasets, that is, Quora, Twitter-URL, SciTail, and SICK-E. Compared with state-of-the-art methods, SEIN achieves the best performance on most datasets. The experimental results proved that introducing external knowledge could effectively improve the performance of the short-text matching models. The research sheds light on the role of lightweight models in leveraging external knowledge to improve the effect of short-text matching.

    Abstract
    Purpose - The purpose of this paper is to explore the communicative rituals of opening and closing manifested in e-mail-based Internet Public Library's (IPL's) online reference interaction. Design/methodology/approach - A total of 400 transcripts comprising user queries and responses by IPL librarians are examined. The opening and closing elements are identified to examine the way in which IPL librarians and users construct social space; that is, communicate their interpersonal and affective stances during the course of seeking and offering information. Findings - The results of data analysis show regular patterns of verbal and structural politeness indicators of opening and closing e-mail discourse. Linguistic elements such as greetings and acknowledgement are included in all the sampled transcripts; i.e. a 100 percent occurrence. Closing rituals have a 95 percent occurrence of linguistic features such as acknowledgement and invitation for follow-up. In contrast, there is a low occurrence of personalized openings through greeting by user name (26 percent). This lack of personalization also occurs in closings: personalized farewell through use of librarian name appears in only 8 percent of closings. Research limitations/implications - The employment of the various politeness tactics in opening and closing reflects the librarian's attention and concern to user's information needs, interests and wants. Such communicative competence narrows social distance and brings forth close socio-interpersonal space for interaction; this may, in turn, improve the overall quality of reference service. Research findings also indicate that more use of personal names may decrease the social distance between the librarian and user, resulting in increased solidarity and proximity. Originality/value - The study provides new insights into linguistic politeness and the functions of address forms such as personal names with a view toward developing effective opening and closing rituals that contribute to the enhancement of virtual reference services.
