A closer look at the values of the network parameters shows that ICWL (and, to a certain extent, ICALT) clearly faces a challenge: the ICWL community is highly clustered into many unconnected components, thus a giant component (a group of core authors) is missing.
Given the comparison of network structures of TEL and database conference communities, and in particular the case of ICWL, we attempt to understand the strategy by which conferences develop their community.
For TEL conferences, the fraction of recurring authors and their publications in ICWL ceased to increase during the last five years.
In more interdisciplinary conferences like ICWL, authors return to the conference at a lower rate.
In this paper we have explored the structural development of the Technology Enhanced Learning (TEL) scientific community by analyzing the development pattern of co-authorship networks of five major international conference series in TEL which have particular relevance for authors who have also published papers in the ET&S journal: ICALT, ICWL, ECTEL, ITS and AIED.
On the other hand, it slows down the process of building a core group of authors, as we saw, for example, in the relatively slow development pattern of ICWL compared to faster developing, more focused conferences like AIED and ITS, which have a clear artificial intelligence focus, or ECTEL, which has its geographic and thematic focus in European TEL.
