[论文解读] Disclosing the network structure of private companies on the web: the case of Spanish IBEX 35 share index
本研究通过识别和分类西班牙IBEX 35公司所关联的附加网域(AWDs),分析其网络结构,发现尽管AWDs具有较高的网络存在感,但其可见性较低,且相互之间的链接薄弱,导致网络密度较低。本研究首次引入一种创新的网页计量方法,衡量AWDs对公司网络表现的影响。
It is common for an international company to have different brands, products or services, information for investors, a corporate blog, affiliates, branches in different countries, etc. If all these contents appear as independent additional web domains (AWD), the company should be represented on the web by all these web domains, since many of these AWDs may acquire remarkable performance that could mask or distort the real web performance of the company, affecting therefore on the understanding of web metrics. The main objective of this study is to determine the amount, type, web impact and topology of the additional web domains in commercial companies in order to get a better understanding on their complete web impact and structure. The set of companies belonging to the Spanish IBEX-35 stock index has been analyzed as testing bench. We proceeded to identify and categorize all AWDs belonging to these companies, and to apply both web impact (web presence and visibility) and network metrics. The results show that AWDs get a high web presence but relatively low web visibility, due to certain opacity or less dissemination of some AWDs, favoring its isolation. This is verified by the low network density values obtained, that occur because AWDs are strongly connected with the corporate domain (although asymmetrically), but very weakly linked each other. Although the processes of AWDs creation and categorization are complex (web policy seems not to be driven by a defined or conscious plan), their influence on the web performance of IBEX 35companies is meaningful. This research measures the AWDs influence on companies under webometric terms for the first time.
研究动机与目标
- 理解附加网域(AWDs)如何影响大型私营企业的整体网络存在感与可见性。
- 研究AWDs与母公司域名之间及其相互之间的网络拓扑结构。
- 评估AWDs对西班牙IBEX 35指数企业网络表现的影响程度与影响。
- 揭示AWD网络中的结构性不透明性,即域名与主域名之间存在不对称链接,但彼此之间连接薄弱。
提出的方法
- 通过网络爬取与域名分析,识别并分类每个IBEX 35公司所关联的所有AWDs。
- 应用网页影响力指标,衡量AWDs与企业域名的网络存在感与可见性。
- 计算网络密度、度中心性以及链接结构的不对称性等网络指标,以评估连接性。
- 使用网页计量分析,将AWDs的表现与主企业域名进行比较。
- 分析链接模式,以检测不对称关系(例如,企业域名链接至AWD,但反之则不然)。
- 根据功能(如品牌、子公司、地区分支机构等)对AWDs进行分类,以评估结构多样性。
实验结果
研究问题
- RQ1AWDs在多大程度上促进了IBEX 35企业整体网络存在感?
- RQ2AWDs在网上的可见性与母企业域名相比如何?
- RQ3AWDs与企业域名之间及其相互之间的网络拓扑结构是怎样的?
- RQ4为何AWDs尽管存在感高,但可见性却低?哪些结构性因素导致了这一现象?
- RQ5不对称链接模式与低网络密度如何影响AWDs的网络影响力?
主要发现
- AWDs表现出较高的网络存在感,但可见性相对较低,表明其传播或可发现性有限。
- 网络密度值较低,表明尽管AWDs与主域名之间存在强烈的单向链接,但彼此之间的连接仍较薄弱。
- AWDs主要以单向方式连接至主企业域名,表明缺乏相互链接或系统性整合。
- AWD的创建与分类似乎缺乏协调,未见有明确的网络政策指导其部署。
- 本研究首次利用网页计量指标,对AWD影响企业网络表现的程度进行了实证测量。
- AWD网络的结构性不透明性可能扭曲网页指标,掩盖母公司的真实表现。
