Abstract- Using Natural Language Processing and Pattern Recognition methods, BCL Technologies has developed a financial data extraction system called SmartXBRL©, that simplifies and automates ways to create a compliant XBRL document. In this paper we describe the steps necessary to extract and tag detailed Notes data in a 10-Q financial document. Methods to identify and extract the face financial tables, Document and Entity Information (DEI), and Parenthetical are also reviewed, in addition to providing updated results.
I. INTRODUCTION
XBRL (eXtensible Business Reporting Language) is a technical standard for describing financial and related data. XBRL is a way to assign standard tags to financial data in reports and systems so the values can be analyzed in context by a computer application. XBRL compliance requires that all disclosure elements in a financial report-every numeric value and supporting reference, including footnotes-must be identified with specific "tags" according to a standardized system. These XBRL tags define the context for the disclosure elements, so that they can be analyzed as structured data.
Using example-based Pattern Recognition methods and combining years of developing both EDGAR filings and natural language processing software, BCL Technologies has developed a simplified and automated way to create a compliant XBRL document. By searching historical tags, we have developed a methodology that displays the closest match to the company's label and/or offers three alternatives, plus a link to extend/customize.
This paper is a follow-up to BCL's previously- published work [14], in order to cover topics which were not included in the previous study: tagging or detailed notes tagging. It also includes updated results for work done in the previous study.
This paper is designed as follows. Section 2 briefly describes a sample 10-Q document. Section 3 gives an overview of previous work done on DEI, Tables, Parentheticals, and Detailed Notes. Section 4 discusses further advances made to Detailed Note tagging. Updated results are given in Section 5. Section 6 concludes and talks about future plans we intend to undertake.
II. QUARTERLY FINANCIAL DOCUMENT (10-Q)
Form 10-Q, used for quarterly reports, is filed after the end of each of the first three fiscal quarters of each fiscal year. It is important to understand the content and structure of an input document (10-Q in this case) before...
