Artificial intelligence for patent classification made easy
Importing Patent Documents
3. Click “Connector Management” on the project overview page
4. Choose “IfiClaimsConnector” and click on “Create connector”
5. Import patent documents that match your individual query
Add a name for the resulting patent collection and at least one of the following search criteria
- a query (see searching guide here)
- an applicant or assignee
- publication dates (format: yyyymmdd)
Typical queries are (in any combination):
Phrases: "solar energy" Boolean-OR: "solar energy" OR "wind power" Proximity: "solar generation"~5 International classification: ic:A61K
Alternatively, you can enter a list of patent ids in the field “UCID List”. Please use the IFI Patent Number Converter to convert your specific format to IFI numbers and use the “Copy to Clipboard” functionality to enter the values.
6. Start importing
Click on – the patent documents are now imported into your application directly from the patent database. This process takes place in the background, which means that you can continue with the next steps.
Creating the classification schema
7. Click on “Label system” on the project overview page to setup the categories
8. Add your individual target categories by clicking on “Create new label”
Training the system
9. Click on „Classification“ on the project overview page
10. Select training data for the assignment of category labels
You will access the search page with some classification filters on the left panel:
- Label: An overview on the assigned labels for the current search result
- Confidence: Either “high”, “low” or empty
- Status: Either “Unclassified”, “Approved” (i.e. manually labelled) or “Auto-classified”
Furthermore, there are filters on the patents metadata:
- Applicant: Aggregation of patent applicants
- IPC4: international patent classification on a 4-character-level
- Source: the name of your collection(s)
Use the search functionalities by using filters and keywords to identify relevant patents for a specific category. There are now three options to label the resulting document set:
- Click on the blue button “Label document(s)” without selecting particular documents: The assignment of a category to choose will be done on whole result set.
- Mark the check box(es) left to the title information: The subsequent assignment via the blue button “Label document(s)” refers to the marked documents only.
- Click on the small tick-mark below the title information of the document. The assignment refers only to that particular document.
11. Choose appropriate category label and confirm with “Save”
12. Getting an overview on the training documents
The facets on the left show the distribution of the training material. For the “Status” filter, click on the value “Approved” and afterwards open the filter “Label”. You will see the category labels together with their frequency of occurrence in the corpus.
13. Training the classifier using Machine Learning
Switch to “Classification Configuration” on the project overview page and click on the mortarboard icon . The “State” of the classifier will be changed to “TRAINING”. Click on to update the current state. When “State” switches to “IDLE” and “Model” to “READY” the classification model has been trained and is ready to use.
14. Evaluation of the classifier
Clicking on will show statistics of the model trained. It depicts an overview on the quality of the predictions in general (top) and for each category (bottom) by taking the measures in terms of precision, recall, f1-score and accuracy (common metrics in machine learning).
Automatic classification of patents
15. Switch to the “Classification” page on the project overview
The newly generated model can be used to automatically classify all previously unexamined documents. There are 3 options:
- Click on the blue button “Classify document(s)” without selecting particular documents: The assignment of a category will be done on all documents with status “Unclassified”.
- Mark the check box(es) left to the title information: The subsequent classification via the blue button “Classify document(s)” refers to the marked documents only.
- Click on the “classify” icon below the title information of the document. The assignment refers only to that particular document.
The first option runs the automatic classification in the backend after some initial processing. Click on the filter “Status” to get the current progress of the classification process.
A confidence value (between 0 and 1) is assigned to each classified document, together with the predicted category. The label will appear in green color when the confidence value is high. If it’s lower, the color is red. Corresponding filters are available on the left panel of the application.
Click on the “Status” filter “Autoclassified”, select a category by using the “Label” filter and choose “Sort by confidence (descending)” and you will receive the most relevant patent documents for that particular category. You can combine these filters with additional ones (e.g. applicants, IPCs keywords, etc.).
16. Improving the classifier through active learning
Sorting the current selection by confidence “ascending” will show documents with predictions that come with a very low confidence. It’s worth to make corrections (or confirmations) to these particular predictions, because the system learns best from those examples where it is uncertain.
Simply click the check mark left or the cross right from the category label in order to confirm or remove the prediction. After some examples the system should be trained again (13), and the resulting performance metrics will increase (14). Use the resulting model to re-classify your patent collection (15).
