In this paper, we focused on a research on a Location-Based Social Network Service to increase social interactions among people who are engaging in research and development. Since existing many of location-based social network services have only provided information of regions and social relations of users have targeted an unspecific majority of groups, they could not have active interactions, compared to users of online communities who have particular use purposes. ConAR what we designed to get over these weaknesses, aims at researches to academically exchange with others and it enables them to have social interactions with people of the same interests by helping them select discussion topics and decide assignment places simply and on impulse. Keywords: Social Computing, Social Interaction, Location-Based Service, Context-Aware Service, Communities, Human Computer Interaction. 1 Introduction Social Networking Service is useful to not only keep friendships with acquaintances, but also make new relationships. Because it is an online service, it is also possible to keep friendships with friends who live far away using this. This service is gradually developing into a variety of forms. For example, Twitter is now used to get news or information useful for life and Academia or Research Gate provides services like theses or projects of researchers for users for an academic exchange. In addition, Location-Based Social Networking Services using location information have been developed with an invention of Smart-phone. In particular, Location-Based Social Networking Service provides not only information of regions like restaurants and transportation, but social networking functions among people who live in the same regions. In spite of these services, however, it is not easy to make social relations with people who have common interests and social networking doesn't work as actively as online community services, because it still aims at an unspecific majority of people. The following scenarios suggest problems of the current Social Networking Services: Sung-Wook in a graduate school has a lot of interests in HCI. He opens research achievements and projects of named researchers in the HCI field and exchanges messages with them using an online Social Networking Service provided
