Through the analysis of Poe＇s works and his life, the influence of anima in Poe＇s soul is explored in this study according to Carl jung＇s theory of archetype. Anima is one of the archetypes, which made both negative and positive influences in Poe＇s life and literary creation, leading him to be the master of poetry and short stories, but also consumed his life and caused his death in the prime. In the study about the influence of anima in Poe, Anima was proved acting as the feminine complement factors in Poe＇s unconscious, and made Poe more sensitive in literary creation. As Poe knew the man＇s world and also understood the woman＇s world, which is the accumulative influence of both negative and positive influences of Anima in Poe, his literary creativity was strong and he had the unique aesthetics.

Runway （2006） is the masterpiece of Alice Munro who is a famous Canadian female writer, concerns about women＇s living status. Through depiction of women＇s living states in some smal which shows her I places of Canada, Munro explores women＇s dilemmas that may lead to their inescapable and hopeless situation. The motif of Runway is running away： running away from family, marriage, religion, virtue, betrayal, and even themselves, but the result of running away is no escape and still lingering at their depressed origins. The cause of this situation is women＇s escape from their inescapable choices, as in the different phases of female＇s initiation some choices do more harm than good. Through the analysis feminine living wisdom about the balance husband, and child of the text and the comparison between different in dilemmas is explored from three aspects： the heroines, choice of Munro＇s religion,

Partial multi-label learning（PML） allows learning from rich-semantic objects with inaccurate annotations, where a set of candidate labels are assigned to each training example but only some of them are valid. Existing approaches rely on disambiguation to tackle the PML problem, which aims to correct noisy candidate labels by recovering the ground-truth labeling information ahead of prediction model induction. However, this dominant strategy might be suboptimal as it usually needs extra assumptions that cannot be fully satisfied in real-world scenarios. Instead of label correction, we investigate another strategy to tackle the PML problem, where the potential ambiguity in PML data is eliminated by correcting instance features in a label-specific manner. Accordingly, a simple yet effective approach named PASE, i.e., partial multi-label learning via label-specific feature corrections, is proposed. Under a meta-learning framework, PASElearns to exert label-specific feature corrections so that potential ambiguity specific to each class label can be eliminated and the desired prediction model can be induced on these corrected instance features with the provided candidate labels. Comprehensive experiments on a wide range of synthetic and real-world data sets validate the effectiveness of the proposed approach.
