Annotations

(Comprehensive) description of the dataset(s) and the corresponding application(s). There is no restriction on the text size.

Example:
Structure activity relationships (SAR) describe empirically derived relationships between the chemical structure and the activity of considered drugs. In a typical SAR problem a set of chemicals of known structure and activity are given, and the goal is to construct a predictive theory relating the structure of a component to its activity. Both available datasets described in [King 92, King 95] concern the classic drug design problem of inhibition of E. Coli Dihydrofolate Reductase by pyrimidines and triazines. Pyrimidine compounds are antibiotics based on a common template to which chemical groups can be added at 3 possible substitution positions. A chemical group is an atom or a set of structurally connected atoms (that can be substituted together as a unit) characterized by well defined chemical properties. Some of these properties are encoded within the background knowledge as facts, e.g. polar(br,polar3) states that a bromin atom has a polarity 3. Different considered pyrimidine compounds are identified by the content of the considered 3 positions. Positive examples represent pairs of drugs, the activity of one being known to be higher then that of the other one. Triazines act as anti-cancer agents by preferentially inhibiting reproducing cells. Like pyrimidines, they have a common template but this one is much more complicated with 5 possible substitution positions. The research goal is to identify the rules for predicting activity of different derived compounds. Formally, this task and its structure is closely related to the pyrimidine problem.

Comments

Comment on peculiarities of the dataset or special terms of use and distribution.

Example:
Two datasets are given: pyramidines and triazines. Both of them can be freely distributed as long as appropriate references are given to the papers mentioned.

Complexity

Give an estimate of the size of the dataset. Depending on the data format this can be in Bytes, number of facts, number of cases + avg. size of case, etc.

Example:
3.5 MB

Contact person(s)

Select one or more contact persons for the dataset from the displayed list. To add yourself or a co-worker to this list of persons, go to the persons-page and select the add-button there.
To select more than one person from the list, select the first entry like usual, then hold down the ctrl-key (this may vary over different operating systems and languages, see below) and select the other contact persons by doing a (left-) mouse-button click on their entry in the list.
As this "multiple selection" varies over different operating systems, languages, and hardware configurations, you should refer to your operating system's manual for "multiple selections" or "multiple selection in list-boxes" in case the described procedure does not work.

You can try out selecting in the example on the right-hand side!
