專業網絡中個人檔案與人脈形成之關連性–以LinkedIn為例

Abstract

專業網絡是一種社會網絡，著重在商業性質的互動關係。LinkedIn是一個專業網絡服務，提供了求職、徵才、推薦介紹以及建立關係，藉以獲得更多的事業機會。在無尺度網絡當中，樞紐是連結的集散中心，具有優先連結及成長性，而LinkedIn的專業網絡中，人脈的形成也具有此兩種特徵，因此趨向於無尺度網絡。在專業網絡中會員透過個人檔案查證對方，而個人檔案記錄著個人的人脈網絡以及其工作經歷、參與群組、專業技能以及推薦函。本研究將提出一個主動的方式擷取LinkedIn平台上的個人檔案資料，並且探討工作經歷、參與群組、專業技能以及推薦函與人脈形成之關連性。最後並提出一個方式預估人脈樞紐的人脈數，以對專業社群網絡人脈的形成有更進一步的了解。

Professional network is a social network focused on the interaction of business relationship rather than personal networking intended to connect friends and family. LinkedIn is a professional network service that provides a platform for seeking career opportunities, job requirement, recommendations, introductions and building relationships for getting more business opportunities. In a general scale-free network, hubs are linked with preferential attachment and growth, while in the LinkedIn professional network, the formation of a network also reveal these two characteristics, therefore considered a sort of scale-free networks. The members in LinkedIn could check each other via memberships in the professional network profile, as well as all the information of personal network, their work experience, participate in groups, and professional skills. Letters of recommendation could also be save in the personal profile. This study will propose an aggressive approach to capture LinkedIn profile on the website and explore the owner's work experience, participation in groups, professional skills, and discuss the strength of relationship between the letters of recommendation and connections which are the key elements to form a social network. This paper proposes a way to estimate a connections hub so that we can have a better understanding about the formation of professional networking connections.
