This repository provides a test collection for dataset search in biodiversity. The test collections consists of 14 questions collected in different biodiversity research related projects and reflecting real user informations needs, a corpus of 372 datasets created in the scope of the BEF-China project and human assessments evaluating which dataset is relevant to a question.
Further information on the BEF-China project can be obtained from the website: https://bef-china.com.
The data-portal is available under this link https://data.botanik.uni-halle.de.
Each dataset is available with the following pattern: https://data.botanik.uni-halle.de/bef-china/datasets/<dataset-number>, e.g., https://data.botanik.uni-halle.de/bef-china/datasets/630
| Question Number | Question |
|---|---|
| Q1 | Name 3 species that occur in the shrub layer. |
| Q2 | Find 3 plant species where root lengths (depth) have been considered. |
| Q3 | Find 3 datasets from oaks where nitrogen content have been measured. |
| Q4 | Find 3 datasets where dry weights from conifers have been measured. |
| Q5 | Which nutrients occur in soil? |
| Q6 | Identify all parameters that are correlated to soil depth. |
| Q7 | Which taxa associated with tree species have been found, for example, insects on host trees? |
| Q8 | Which soil samples in BEF-China data show a low pH value? |
| Q9 | Does tree diversity reduce competition? |
| Q10 | Do the soil carbon concentrations increse with soil depth? |
| Q11 | Are there data about the leaf area index (LAI) and in particular in combination with diversity? |
| Q12 | How does tree height have been measured in BEF-China experiments? |
| Q13 | How does the nitrogen cycle interact with water? |
| Q14 | How significant is the role of throughfall as water input to the forest floor? |
The human assessments are available in the provided txt file complying with the TREC benchmark data format. An entry in the txt file looks as follows:
1 0 161 1
The first number denotes the question number, the second number provides the dataset number, the third number denotes the relevance judgment (1-relevant) and the last number is the timestamp of the creation of the entry. All datasets of the corpus that are not mentioned for a question are not deemed relevant.
