    • A method for identifying names of uninformative functions in call-stack traces is described. The method comprises the steps of obtaining a set of call-stacks and information indicative of which call-stack traces in the set match a particular call-stack trace; for each matching call-stack trace pair, incrementing a false negative counter for each function name above a first matching function name in a respective call-stack trace pair; for each non-matching call-stack trace pair, incrementing a false positive counter for each function name above a first non-matching function name in a respective call-stack pair; incrementing a frequency counter for each function name appearing in each of the call-stack traces; calculating an aggregate value for each of the function names as a function of respective ones of the false positive counter, the false negative counter and the frequency counter; and identifying uninformative ones of the function names based on the respective aggregate values. The method may be used to diagnose software problems based on known software problems and is useful in helpdesk and autonomic computing applications. A system and a computer program product for performing the method are also described.
    • 描述了一种用于识别呼叫堆栈跟踪中的非信息功能的名称的方法。 该方法包括以下步骤:获得一组呼叫栈和指示该集合中的哪个呼叫栈跟踪与特定呼叫栈跟踪匹配的信息; 对于每个匹配的调用堆栈跟踪对,在相应的调用堆栈跟踪对中的第一匹配函数名称之上增加每个函数名称的假负计数器; 对于每个不匹配的调用堆栈跟踪对,在相应的调用堆栈对中的第一个不匹配的函数名称之上增加每个函数名称的伪正计数器; 为每个呼叫栈跟踪中出现的每个功能名称递增频率计数器; 根据假阳性计数器,假负计数器和频率计数器中的各个函数计算每个函数名称的汇总值; 并基于相应的聚合值来识别功能名称中的不知情的一个。 该方法可以用于基于已知软件问题诊断软件问题,并且在帮助台和自动计算应用中是有用的。 还描述了用于执行该方法的系统和计算机程序产品。
