Limits and Future Research Directions
This system has some certain limits of itself, namely
The links embeded in the articles
are added by human experts, which is a tedious and time consuming
task. In our future work, it should resort to automatic
links generation. Although automatic links generation may add
some meaningless links, even bad links into the articles, it can really
find some hidden links which cannot be explicitly found by human beings.
I believe that automatic link generation is a promising direction
in hypertext system research.
- The efficiency of this system is not satisfying. The
index is built for each node of an article, thus a lot of ad-hoc searching
and computations occur during users' queries. New methods should be
developed to improve the system in terms of processing efficiency.
- This system is in a closed domain and it does not interact
with materials outside, especially on the Internet. This problem should
be overcomed by extending the links to outer links, not only inner links.
- Since this system is developed based on an Encyclopedia,
it is not necessarily fit for scholarly article set. For scholarly paper
collections, more indicative materials can be utilized, such as abstracts,
conclusions and references. In fact, references and bibliography can
be considered as natural links to other works. More work should be done
on automatic links among scholarly articles. Some initial work has been
started in Citeceer,
which is a computer science paper search engine and links papers together
using their references and bibliographies.
