| + | Several files (//Education.docs//, //Education.word.vocab//, //Education-multi.dat//, and //Education-seq.dat//) need to be generated in advance in the directory <color red> data/DTM</color> by running <color red>Converter2DTM.java</color> in the package <color red>cn.edu.bjut.dtm</color>. | ||
| + | On the basis of these generated files, theme structures can be discovered with the DTM model with the number of topics $K \in \{5, 10, \cdots, 50\}$ by running the following commands. | ||
| <code bash> | <code bash> | ||
| - | > run_dim_education.sh 40 | + | > nohup ./run_dtm_education.sh 5 >> Education/log5.txt 2>&1 |

| + | > nohup ./run_dtm_education.sh 50 >> Education/log50.txt 2>&1 | ||

| + | |||
| + | For the sake of identifying a proper number of topics, the perplexity is calculated for each $K \in \{5, 10, \cdots, 50\}$ by running <color red>DTMTuningParam.java</color> in the package <color red>cn.edu.bjut.dtm</color>. In the end, $K$ is fixed to 30 in our case. | ||
| + | |||
| + | Then, one can output top words for each topic and topic distribution for each document by running <color red>DTMPrinter.java</color> in the package <color red>cn.edu.bjut.dtm</color>. In this time, two files (//Education.twords// and //Education.vartheta//) will be generated. | ||
